Question

Look at the triangle. What is the approximate value of x​

Answer 1

0.03

Explanation:

In given triangle,

perpendicular(p)=45

base(b)=30

x=?

We know,

tanx = p/b

or, tanx = 45/30

or, tanx = 3/2

or, x = tan-1(9/7)

or, x = 56.3099324740202 i.e. 56 approximately

Answer 2

relationship between perpendicular and base is given by tan angle

tanx°=p/b

tanx°=45/30

x°=tan-¹(45/30)=56.30=56
